Abstract:
During floristic investigation of the northern Greek flora, emphasis was laid on the genera Hieracium and
Pilosella. As a result, six species and three subspecies of the genus Hieracium and three species of the genus
Pilosella were detected in Greece for the first time and reported here. According to the original description
and classification, three of these are suggested as meriting the species rank.
Key words:
Greece, Hieracium, new records, Pilosella, taxonomy
Introduction
Recent checklist of the vascular flora of Greece (Dimopoulos & al. 2013, 2016) reflects remarkable diversity of the genera Hieracium L. and Pilosella Vaill.
(Asteraceae) in Greece. Many of these species belong
to endemic sections of the Balkan Peninsula or have
their center of evolution and diversity in this area, i.e.,
the Hieracium sect. Bracteolata Zahn, H. sect. Cernua
R. Uechtr., H. sect. Naegeliana Zahn ex Szeląg and H.
sect. Pannosa (Zahn) Zahn.
As with the entire flora, the basic set of the Greek
Hieracium species had already been detected in the
“golden age of botanical exploration of Greece” (Dimopoulos & al. 2013) by Heldreich and Orphanides
and described by Boissier in the middle of the 19th century (Boissier 1842–1859). Later collections made by
Sintenis, Haussknecht, Baldacci, Halacsy, Bornmüller
and others were evaluated and determined by Freyn
(1895, 1897) and Zahn. This resulted in about six new
descriptions by Freyn (partly with Sintenis) and many
more by Zahn (1921–23), mainly in his last monographic account for Ascherson & Graebner’s Synopsis
der Mitteleuropäischen Flora (Zahn 1922–38). Zahn
did not limit himself to the actual geographical range
in this publication; rather, he extended his tremendous work to all species of the genus across the Balkans and up to Greece.
In the second half of the 20th century, several new
Hieracium species were described (Buttler 1991). They
were followed only recently with some lectotypifications by Szeląg (2014). Collection activities generally
remained on a rather low level. Hieracium specimens
were mostly gathered unsystematically, as “bycatches”
of other botanical projects.
In several recent materials seen by one of the authors (G.G.), some collections proved to be new taxa
for the Greek flora (Gottschlich & al. 2006, 2013,
2014). This led to a hypothesis that a more systematic
collection activity with special emphasis on Hieracium
and Pilosella would substantially increase the knowledge about these genera in Greece. This assumption
has been sustained by collections of the first author
since 2012.
The new field project “Hieracium and Pilosella in Greece” has started in the northern parts of the
country (Epirus, West, Central and East Macedonia
218
Dunkel, F. & al. • Hieracium and Pilosella taxa, new for the Greek flora
(Fig. 1). Here, in the granite mountains of Central and
East Macedonia, the highest biodiversity could have
been expected. Indeed, a richness of different species
was found combined with high local abundance along
the forest roads, especially bordering on the woods
and on decomposed granite slopes. In the calcareous
mountains, habitats rich in species of Hieracium and
Pilosella are restricted to subalpine and alpine meadows, screes and rocks.
As a result of the present investigation, twelve taxa
(nine species, and three subspecies) have been newly
found for Greece. Three taxa were suggested as warranting the rank of species, according to the original
description.

Hieracium argyrotrichum Freyn
≡ H. olympicum subsp. argyrotrichum (Freyn) Zahn
Hieracium argyrotrichum is recorded for Greece as H.
olympicum subsp. argyrotrichum (Freyn) Zahn. Al-
though H. olympicum shows great morphological variation, H. argyrotrichum differs substantially from this
species. The shape of the broad lower leaves is similar
to that of H. racemosum (see Szeląg 2014: Fig. 2). Therefore, H. argyrotrichum can be interpreted morphologically as an intermediate species “olympicum > racemosum” and should be treated in the rank of species.

Hieracium crinitopannosum Szeląg & Vladimirov
This recently described species is known from the
Central Rhodopes of Bulgaria (Szeląg & Vladimirov
2013). Morphologically, it is very similar to the collective species H. chalcidicum Boiss. but differs by its
sharply dentate leaves. Now, it can also be documented as occurring in the Greek parts of the Rhodope
Mountains.

Hieracium klisurae Zahn ex Urum.
Hieracium klisurae s. str. has been known so far only
from Bulgaria (SOM-13080!, SOM-89659!). It can be
regarded as intermediate between H. sparsum and H.
racemosum. Both presumptive parents are very common in the Rhodope Mountains. However, the character of the species – a primary recent or stabilized hybrid? – is so far unknown.

Hieracium olympicum subsp. permulticeps

the type subspecies (G!) by its large basal leaves, which
are strongly dentate.

Hieracium penzesii Kováts & Zahn ex Pénzes
≡ H. jankae subsp. penzesii (Kováts & Zahn ex
Pénzes) Greuter
Hieracium penzesii can be regarded as a forgotten species. Described just before the World War II in a new
but little-known journal (Pénzes 1939), it was never adopted in the Bulgarian floras (Stojanov & Stefanov 1948; Stojanov & al. 1967 and Assyov & Petrova 2006). Only Greuter listed it recently (Greuter &
Raab-Straube 2007). According to the estimation of
H. jankae as “sparsum > pannosum” by Zahn, Greuter transferred it to H. jankae in the rank of subspecies. However, H. jankae is densely villous in all parts
and possesses subplumose hairs. Contrary to H. jankae, H. penzesii is only covered with (not subplumose,
only distinctly dentate) hairs on both surfaces of the
leaves. The upper part, including the synflorescence,
is almost glabrous and resembles completely H. sparsum (isotype: B-101024849! represents a plant that is
not completely developed; a better one is illustrated in
Fig. XVII in Pénzes 1939). Therefore, the taxonomical
circumscription of H. jankae does not correspond at
all to the plants that were found. Summarily, H. penzesii is set apart from H. jankae, and its ranking with
species seems to be more appropriate.

Hieracium sparsum subsp. werneri (Szeląg) Greuter
(Fig. 3)
This taxon has been known so far only from Bulgaria, but it also grows in the Greek part of the Rhodope
Mountains. It differs from subsp. sparsiceps (Zahn) Zahn
by a greater number of cauline leaves (Szeląg 2006).

Hieracium subnitens Zahn (Fig. 4)
This species has been treated as H. sparsum subsp. subnitens in the Euro+Med Plantbase. However, the shape
either of basal or stem leaves differs strongly from all
taxa of H. sparsum (see Fig. 21 in Szeląg 2015). The
entire plant looks like a relative of the Central European H. lachenalii. Therefore, we contend for the original rank of species.

Hieracium villosum Jacq. (Fig. 5)
2016). Therefore, the hybrid, P. biglana, was expected in Greece, too, and could now be confirmed for the
country.
H. villosum is well known in the Alps and also occurs
on the Balkan Peninsula. From Albania, there have
been several historically known but only one recent
collection adjacent to the Greek border (Gottschlich
& Barina 2017:129). Thus, the occurrence of H. villosum on Mt Gramos is not surprising.

Pilosella cymosiformis (Froel.) Gottschl.
P. pavichii and P. leucopsilon (= Hieracium hoppeanum
subsp. testimoniale) are common species in North
Greece. P. leucopsilon seems to be always sexual; P.
pavichii either sexual or apomictic (Krahulcova & al.
P. cymosiformis (= H. fallax auct. non Willd.,
Gottschlich 2013) is interpreted as an intermediate
species “echioides – cymosa”. Records from Hungary,
Serbia and Romania are very scanty.

Pilosella serbica (F.W.Schultz & Sch.Bip.) Szeląg

= Hieracium alpicola subsp. glandulifolium Nägeli &
Peter
Fig. 5: Hieracium villosum (Du-34503, Go-68091).
The Pilosella alpicola group comprises four vicariant
species of perennial herbs (Szeląg 2008, Šingliarová
& Mráz 2009) characterized by their large capitula with a silky hairy involucrum. Recent studies have
shown that the taxa of this group are very closely related and diverged relatively recently, but morphologically are well defined (Šingliarová & al. 2011). At
the Greek site, P. serbica grows among large populations of P. rhodopea (Rchb.) Szeląg. The former differs from P. rhodopea by black, up to 0.5 mm long
glandular and sparse to scattered 3–4 mm long, simple hairs instead of dark-grey, up to 3 mm long glandular hairs and sparse, 2–3 mm long simple hairs at
the peduncles. Both taxa display contrasting cytogeographic patterns with different cytotypes. P. serbica is
diploid and outcrossing. It has only been known from
Montenegro and Serbia. The Balkan taxon P. rhodopea
